Patent GB-846614-A (GB)
Title: A process for the preparation of aqueous gels from amides of polyuronic acids
IPC: A23L29/256
Filed: 1958-02-18
Abstract: Aqueous gels are prepared by dissolving a polyuronic acid amide, at least half of whose acyl groups are present as carbonamide groups and the remainder substantially as neutralised carboxyl groups, in excess amounts of water in the presence of a lactone of a hydroxy acid or an organic acid anhydride as acid-forming substances.  The polyuronic acid amide and the lactone or anhydride may be mixed together, if desired with the addition of further substances, to form compositions which form aqueous gels on addition to water.  The term "polyuronic acid" is defined to include cellulose glycollic acid and the preferred amides used are those of alginic acid, pectic acid and cellulose glycollic acid.  These amides should contain 0,5 to 1,5 acyl groups per uronic acid unit, about 50-80% of these acyl groups being carbonamide groups and the remainder being neutralised with ammonium ions or monobasic organic or inorganic bases.  Preferred acidforming substances are the lactones of sugar acids, such as gluconic acid lactone or mannuronic acid lactone, and glycollic acid anhydride.  In forming the aqueous gels generally less than 30 parts by weight of polyuronic acid amide are used per 100 parts by weight of water and 10-100 parts by weight of acid forming substance per 100 parts of amide.  Firmer gels are obtained when polyvalent metal ions such as calcium, magnesium or aluminium ions are present in amounts of less than 1% by weight based on the amides.  Though the aqueous gels may be formed in the cold, the solution of the gel-forming substances may be accelerated by working at elevated temperatures up to 100 DEG C.  The gels prepared may be used for the preparation of culture media for microorganisms, for pharmaceutic and cosmetic preparations and for the preparation of jelly-like foods (see Group VI). Specification 768,309 is referred to.ALSO:Jelly-like foods are prepared without heating by dissolving in excess water or aqueous liquid an amide of a polyuronic acid at least half of whose acyl groups are present as carbonamide groups and the remainder substantially as neutralised carboxyl groups, and a lactone of a hydroxyacid or an organic acid anhydride, together with a content of flavouring.  The amides of alginic acid, pectic acid or cellulose glycollic acid may be employed in these preparations.  Suitable lactones are gluconic acid lactone or mannuronic acid lactone, and glycollic acid anhydride is a suitable anhydride.  The polyuronic acid amide and the lactone or anhydride together with a content of flavouring may be mixed together to form food compositions which, after mixing with some aqueous liquid, e.g. fruit juice, wine or milk or with water itself, provide jelly-like foods of good appearance. These foods may be eaten as such or further processed, for example for the production of ice-cream and similar frozen foods.  Examples describe the preparation of chocolate and vanilla puddings with milk powder and whole milk.  Specification 768,309 is referred to.

Title: Improvements in calculating machines
IPC: G06F7/44
Filed: 1937-02-22
Abstract: 492,748. Calculating-apparatus. HOFGAARD, R. Feb. 22, 1937, No. 5202. [Class 106 (i)] In a machine employing an electrical circuit arrangement wherein each result is determined by the closing of the proper circuit or circuits each denominational order is provided with a plurality of registering or accumulating devices less in number than the radix of the numerical system employed and each device has a member adjustable into various positions representing multiples of the numerical value of the corresponding device. The machine also includes a number of multicontact relays, manually operated switches or keys for entering the items and factors of a multiplication, and control switches for determining the nature of the calculation to be performed by the machine. In the machine described the accumulating devices are formed as electromagnetically operated step selectors, each having a plurality of sets of multiple contacts. As shown in Figs. 2 and 3, each step selector has an adjustable member, or roller i with projections q for operating in succession rods r of insulating-material and formed with notches for the reception of contact springs u that co-operate with fixed contact bars v. The roller i is adjusted step by step through gearing and a ratchet drive j, m by the operation of the armature k of an actuating electromagnet h. The number of selectors in each denomination for the decade system is four representing the values 1, 2, 4 and 8 for the units and the values 10, 20, 40 and 80 for the tens. For subtraction operations the appropriate control switch is operated whereby certain circuits are closed through the appropriate relays and the complement of the number to be subtracted is added to the number accumulated on the selectors. For multiplication, operation of the key switches corresponding to the value of the factors controls appropriate multi-contact relays to effect the closure of precalculated circuits to transmit impulses in accordance with the code values of the product to the appropriate selectors in the several denominations. For printing the result of a calculation the leads from the denominational selectors may be switched over to the contacts of the relays 268, 269, Fig. 10, for controlling the operation of magnets 282 ... 291 and 292 ... 301 whereby the differential movement of type bars 302, 303 for the units and tens values may be controlled. To effect an impression a handle 308, Figs. 9 and 10, is rotated through 180 whereby an eccentric roller 307 permits the type bars to rise until arrested by the projecting stops engaging the actuated armatures of the magnets. A boss 309 by striking an arm 310 operates an impression hammer 311 to strike a paper strip and carbon ribbon against the type. Circuit arrangements and selectors are described by means of which the result may be expressed according to the diodecinal system and a system having " 20 " as radix. Specifications 224,549, 302,237, 314,026, [all in Class 106 (i)], and 410,129 are referred to.
